“…After thoroughly assessing the completeness of the downloaded genomes of Hafnia, contamination, and nucleotide identity scores, we used the retained highquality genomes to perform a comprehensive tracking analysis within the main environmental sources of Hafnia strains providing an ecological overview of the distribution of this bacterial species (Data Set S2). Among the environmental sources available, honeybee gut and raw milk cheese were chosen for this study due to recent literature identifying Hafnia as a common pathogen in bees and a prevalent bacterial species in fermented foods and related food spoilage processes (McCarthy et al, 2023). Therefore, we selected 128 deep-shotgun metagenomics datasets from food-dairy samples (Fontana et al, 2023) and 158 metagenomics datasets from honeybee gut samples (additional details in material & methods) to track Hafnia strains with an in silico approach.…”

The bacterial genus Hafnia has recently attracted attention due to its complex metabolic features and host‐interaction capabilities, which are associated with health benefits, primarily weight loss. However, significant gaps remain in our understanding of the genomic characteristics of this emerging microbial group. In this study, we utilized all available high‐quality genomes of Hafnia alvei and Hafnia paralvei to uncover the broad distribution of Hafnia in human and honeybee guts, as well as in dairy products, by analysing 1068 metagenomic datasets. We then investigated the genetic traits related to Hafnia's production of vitamins and short‐chain fatty acids (SCFAs) through a comparative genomics analysis that included all dominant bacterial species in the three environments under study. Our findings underscore the extensive metabolic capabilities of Hafnia, particularly in the production of vitamins such as thiamine (B1), nicotinate (B3), pyridoxine (B6), biotin (B7), folate (B9), cobalamin (B12), and menaquinone (K2). Additionally, Hafnia demonstrated a conserved genetic makeup associated with SCFA production, including acetate, propanoate, and butanoate. These metabolic traits were further confirmed using RNAseq analyses of a newly isolated H. paralvei strain T10. Overall, our study illuminates the ecological distribution and genetic attributes of this bacterial genus, which is of increasing scientific and industrial relevance.
